Abstract
A new tool package written in Interactive Data Language (IDL) was developed for
processing and analyzing daily continuous GPS position time series. This
software package can read continuous GPS position time series in various formats,
detect outliers, remove abnormal observation spans, locate epochs of offsets or
post-seismic relaxation events, and estimate their amplitudes. It also provides
functionalities for epoch statistics, site selection, periodic noise analysis,
spatial filtering (by regional stacking), etc. This tool is referred to as iGPS.
The IDL code (and sample data files) are available from the sourceforge website:
